Case 404: Universe not found

All Rights Reserved ©

Summary

At exactly 1:13 AM, the notebook changes. Struggling mini-drama actor Lu Chengyan lives a quiet, exhausting life of overnight shoots, forgettable roles, and empty apartments—until a mysterious notebook begins writing messages on its own. The victim in Apartment 404 was not the target. Minutes later, the murder appears on the news. Terrified yet unable to ignore the impossible warnings, Chengyan becomes entangled in a series of crimes connected to details no one should know. But the messages are not coming from a hacker or a ghost. They are coming from another universe. In a parallel reality, detective Lia Shen has spent years investigating murders that defy logic—victims with impossible timelines, witnesses remembering events differently, and evidence that appears before crimes even happen. Every case leads back to the same impossible phenomenon: 1:13 AM. As Chengyan and Lia begin communicating through the notebook, they uncover a terrifying truth hidden between worlds: someone is deliberately tearing realities apart. The deeper they investigate, the more unstable both universes become. People disappear from photographs. Memories rewrite themselves overnight. And the closer Chengyan and Lia grow, the more reality itself begins rejecting their existence. Because twenty years ago, someone tried to force two universes together— …and the fracture never truly closed. Now, bound by a connection neither fully understands, an exhausted actor and a detective from another reality must solve the mystery before both worlds collapse completely. Even if saving reality means losing each other forever.

The Things People Don't Notice


Rain hammered relentlessly against the studio rooftop while artificial snow drifted across the filming set in thick white waves.

Under blinding production lights, Lu Chengyan died beautifully for the third time that night.

His body collapsed against frozen concrete, fake blood staining the corner of his lips while snow settled slowly over his dark coat. The cameras pushed closer, capturing every trembling breath, every crack in his expression.

Then silence.

The director stared at the monitor for exactly two seconds before slamming his script against his thigh.

“Cut!”

The rooftop instantly came alive.

“That’s it!” The director pointed dramatically toward the monitor. “That crying scene just saved the entire episode.”

Scattered applause erupted across the set. One of the lighting staff even wiped fake tears from his eyes.

“Brother, why are you suffering this attractively?”

Laughter spread immediately.

Meanwhile, Chengyan remained motionless beneath the artificial snow.

One of the makeup artists narrowed her eyes suspiciously.

“…Is he actually asleep?”

A production assistant cautiously walked over.

“Chengyan?”

No response.

Another pause.

Then someone shouted from behind the camera crew—

“If you don’t get up now, they’re going to zip you into an actual body bag.”

The rooftop exploded with laughter.

Slowly, Chengyan opened one eye.

“…Tempting.”

The exhausted lighting crew started clapping sarcastically while someone yelled, “Method acting!”

A production assistant reached down and helped pull him upright.

“Seriously,” she said, “how are you still functioning?” “You’ve been filming for thirty hours.”

Chengyan accepted the water bottle handed to him with the solemn dignity of a dying soldier.

“Hatred.” A sip. “Caffeine.” Another sip. “And unresolved financial trauma.”

The makeup team nearly collapsed laughing.

People naturally crowded around him afterward—someone fixing his coat, another touching up his makeup, someone else adjusting his microphone even though filming had already wrapped.

That was the strange thing about Lu Chengyan.

People liked being around him.

Not because he was the biggest celebrity on set. He wasn’t.

Not yet.

He was stuck in the strange middle ground between recognition and obscurity. Popular enough that clips of his scenes spread online within minutes. Popular enough to attract dedicated fans who dissected every expression he made.

But not famous enough to stop accepting low-budget mini dramas with overnight schedules and collapsing production timelines.

Still, Chengyan remembered everyone’s names. Bought coffee for exhausted staff members without being asked. Stayed polite even after thirty-hour shoots. Never snapped at assistants. Never acted superior.

Warmth came naturally to him.

Maybe because life had once been cruel enough that he understood exhaustion too well.

One of the younger actresses suddenly gasped while scrolling through her phone nearby.

“Oh my God.”

She rushed toward him excitedly.

“Someone already uploaded your death scene.”

Chengyan blinked slowly. “That was filmed six minutes ago.”

“The internet works fast.”

She shoved the phone toward him.

Comments flooded endlessly beneath the clip.

HE LOOKS SO GOOD CRYING

WHO HURT THIS MAN

LU CHENGYAN, PLEASE STOP SUFFERING BEAUTIFULLY

I KNOW HE’S ACTING BUT I FEEL GUILTY

Chengyan stared quietly for a moment before snorting.

“Concerning behavior.”

His manager appeared beside him almost instantly holding two phones and what looked like severe emotional damage.

“Stop flirting with your fans and go change.” “You still have an interview tomorrow.”

“That wasn’t flirting.”

“You smiled.” “Same thing.”

The actress beside him nodded seriously. “Honestly? Your fans would survive on eye contact alone.”

“…That sounds medically dangerous.”

More laughter broke out.

Near the monitors, the director lit a cigarette before pointing toward Chengyan.

“See?” “This is why audiences like you.” “You look approachable.”

Chengyan smiled politely again.

Easy. Natural. Practiced.

But for one very brief second— after everyone looked away—

the smile disappeared completely.

Not sadness.

Not loneliness.

Just exhaustion.

The quiet kind people only notice when nobody else is paying attention.


By the time filming finally wrapped, the city outside had nearly fallen asleep.

Rain still poured steadily across neon-lit streets while the company van moved silently through wet traffic. Chengyan leaned against the window with his hood pulled low, watching distorted reflections slide across the glass.

The exhaustion inside him felt heavy tonight.

Not physical.

Something deeper.

The company van eventually stopped outside his apartment building beneath flickering streetlights.

Before Chengyan stepped out, his manager lowered the driver-side window.

“Don’t forget tomorrow’s schedule.”

“I won’t.”

“And answer your mother’s messages.” “She called me instead of you again.”

Chengyan looked genuinely offended.

“Traitor.”

“Pay your debt installments on time and maybe I’ll regain loyalty.”

“Wow.” “Capitalism really destroys friendship.”

His manager pointed directly at him.

“Go sleep.”

A quiet laugh escaped Chengyan before he shut the van door.

Rain misted softly against his coat as he entered the apartment building. The lobby was empty except for the buzzing fluorescent lights overhead.

The elevator groaned during the ride upward.

Seventh floor.

The hallway lights flickered once.

Then again.

Chengyan frowned slightly.

Strange.

The digital clock above the elevator reflected faintly against the metal walls.

1:13 AM.

The lights stabilized immediately afterward.

Silence returned.

Too tired to think much about it, Chengyan unlocked his apartment door while removing his cap.

Darkness greeted him instantly.

Cold air. Scattered silence. An apartment untouched by warmth.

Still faintly smiling from earlier conversations, he tossed his script onto the kitchen counter carelessly. Several loose pages slipped free and scattered across the floor.

One page flipped over beneath the dim kitchen light.

A line from the script stared back at him.

“Even if the world ends, I’ll find you again.”

Chengyan stared at it briefly before laughing softly to himself.

“Dramatic nonsense.”

He loosened his jacket and disappeared deeper into the apartment.

Behind him—

inside the darkness—

a single page quietly turned by itself.


Lu Chengyan woke up with his face pressed against a script.

For several long seconds, he genuinely couldn’t remember when he had fallen asleep.

Or why his neck hurt this badly.

Then reality slowly returned.

The couch. The scattered papers. The cold apartment air. Rain still falling faintly outside.

“…I’m getting too old for this.”

His tired voice echoed softly through the empty apartment.

The digital clock near the television glowed faintly.

7:48 AM.

He had exactly forty minutes before his team arrived.

Fantastic.

Chengyan dragged both hands down his face before forcing himself upright. Pale gray morning light leaked weakly through the curtains, barely warming the apartment.

At some point during the night, he had apparently forgotten to eat again.

Cold takeout still sat abandoned near the couch.

He stared at it.

Then sighed.

“You deserved better than this.”

The container offered no emotional response.

Still half asleep, Chengyan wandered toward the kitchen and reheated yesterday’s coffee instead.

A terrible decision.

He drank it anyway.

His phone immediately buzzed nonstop across the counter.

Manager:

WHERE ARE YOU

Manager:

Please tell me you’re conscious

Manager:

If you die before becoming famous, I’ll actually kill you

A tired laugh escaped him.

Then another notification appeared beneath them.

Mother.

Did you sleep properly?

A second message followed shortly afterward.

Don’t skip meals again.

Something in his expression softened slightly.

Without hesitation, Chengyan transferred money into her account.

Almost half of what remained from this month’s earnings.

A few seconds later, his phone rang.

“Morning,” he answered quietly.

“Did you just send me money again?”

“That’s usually how bank transfers work.”

“Chengyan.”

Her voice carried immediate disapproval.

“You need to keep more for yourself.”

He leaned against the kitchen counter, staring at the rain outside the window.

“I’m surviving.”

Silence lingered afterward.

Not awkward.

Just tired.

Then softly, his mother asked,

“Are they still overworking you?”

Chengyan glanced around the apartment.

At the unpaid bills near the table. The scripts scattered everywhere. The exhaustion permanently buried inside his bones.

Then he answered lightly anyway.

“That means work exists.” “I should be grateful.”

His mother became quiet after that.

Because both of them understood what he wasn’t saying.

There had once been years where work disappeared completely. Where calls stopped coming. Where debt collectors sounded louder than opportunity.

Years after his father died—

when everything in their lives began collapsing slowly.

His father had once been respected.

Before the investigations. Before the obsession. Before people started whispering words like unstable and mentally ill behind closed doors.

Even now, nobody mentioned him directly anymore.

Just lowered their voices carefully around the subject.

Chengyan hated that.

Because despite everything, his father had once been warm. Funny. Curious about everything.

Not the broken man people remembered at the end.

His mother’s voice softened again.

“Are you coming home next month?”

Right.

The memorial anniversary.

Chengyan closed his eyes briefly.

“…I’ll try.”

Not a lie.

But not quite a promise either.

After the call ended, silence filled the apartment once more.

Not loneliness exactly.

Just the feeling of carrying too much alone for too long.

Rain tapped quietly against the windows.

The reheated coffee had already gone cold beside him.

Then suddenly—

his phone buzzed violently.

Manager.

“If you’re still alive, open the door.”

Chengyan blinked.

A second later—

BANG. BANG. BANG.

“LU CHENGYAN.”

More knocking.

“I KNOW YOU’RE HOME.”

Despite himself, Chengyan laughed.

Actually laughed.

And somehow—

the apartment didn’t feel quite as empty afterward.
